The die-hards will likely stay in Europe while the cowards will flee to America. In Zimbambwe, there are still some Whites living there despite all of what happened under Mugabe’s regime.
I'm not sure that will be the case with Europe. I expect that the cowards will remain and do nothing until they get their dhimmi lapel pin. That's what they are doing now. The die-hards seem to be the ones emigrating to the US, Canada and Australia etc. They can see the writing on the wall.
